Specifications subject to change without notice.
Designed to meet today's
requirements for 3.3V Differential
LVPECL applications. The
CVPD-914 is produced using
mesa crystal design to provide a
very low noise, low jitter voltage
controlled clock oscillator for
demanding telecom and other
applications.
